COMMODITY KEY CONTROL FOR TWO PRINTERS

摘要

COMMODITY KEY CONTROL OF TWO PRINTERS A system for weighing and labeling random weight packages of commodities includes a weighing scale, a price computer, and printers for printing both human readable and machine readable information. A commodity key includes a printing area for reproducing readable commodity identification and coded identification which is used to produce machine readable commodity identification. Entry of the key into the human readable printer also enters the coded identification. A second computer coacts with the machine readable label printer to produce a unique check character which is included in the printed information. Two labels are supplied, unique to each package, and are so presented from the printers that the label applicators guide the package to align the two labels on opposite sides of the package.
